1.1 Cable Description
The fibers, 250 μm, arepositioned in a loose tube made of a high modulus plastic. The tubes are filledwith a water resistant filling compound. The tube is wrapped with a layer ofPSP longitudinally. Between the PSP and the loose tube water-blocking materialis applied to keep the cable compact and watertight. Tow parallel steel wiresare placed at the two sides of the steel tape. Then, the cable is completedwith a PE sheath.
1.2 Cable Characteristics
l Good mechanical and temperature performance
l High strength loose tube that is hydrolysis resistant.
l Special tube filling compound ensure a critical protection of fiber.
l Crush resistance and flexibility.
l PSP enhancing moisture-proof
l Tow parallel steel wires ensure tensile strength
l Small diameter, light weight and easily installation
1.3 Cable Application
l Long-distance communication.
l It's suitable for duct, especially for the placeswith high requirement for moisture-proof.
l Installation: Duct, direct-buried Or self-supporting aerial
